Abstract: ABSTRACT OF THE DISCLOSURE         In a drill with an electric motor positioned within a motor space, air for cooling the motor is drawn in through an inlet manifold and discharged through an outlet manifold.    The inlet and outlet manifolds are constructed to prevent the flow of water into contact with the motor.  A hood-like deflector is provided over the entrance into the inlet manifold.          Further, filters located within the manifolds remove any water in the air.  A labyrinth air passage conducts the air from the inlet manifold into the motor space.

Abstract: Abstract of the Disclosure An improved method and apparatus for ingesting and melting metal scrap that otherwise tends to float on the surface of a molten melting media.  The method includes the steps of providing a supply of the melting media and directing the media from the supply to an upper portion of a receptacle having an outlet opening in the lower portion thereof.  The flow of the melting media entering the receptacle produces a free vortex of the media in the receptacle, as the media flows out the lower opening.  The amount of the flow of the melting media to the receptacle and the size of the lower opening are such that a predetermined level of the media is maintained in the receptacle. The symmetry and continuity of the flow pattern of the vortex are disturbed in such a manner that floating metal solids (and any associated skim material) entering the vortex from the upper portion of the receptacle are rapidly ingested into the melting media.  Such ingestion is much more effective than the limited ingestion capability of an undisturbed vortex.

Abstract: ABSTRACT OF THE DISCLOSURE        The wall-mounted dispenser for liquid soap has a separable reservoir with an outlet valve.  The dispenser further includes a main body with a second outlet valve.  When the reservoir is mounted to the main body, a metering chamber is defined between the two outlet valves.  The dispensing function is experienced by pushing in a plunger which temporarily decreases the chamber volume and forces the main body outlet valve to open temporarily, thus dispensing a charge of liquid soap.  As the plunger is released, a spring return pushes the plunger out, decreasing pressure in the metering chamber, which is equalized as the first outlet valve temporarily opens, admitting a next charge of liquid soap from the reservoir t the metering chamber. The reservoir is replaced by pushing in a resilient release, but the resilent release is preferably normally provided with a stop which must first be moved out of the way.  This is to prevent the user from accidentally disconnecting the reservoir when what is really wanted is a dispensation of soap.  Should the reservoir be disconnected, pushing in and releasing the plunger will not result in the first outlet valve to open, because pressure will not be lowered in the metering chamber when the plunger is released.

Abstract: MOUTHPIECE FOR RESUSCITATION  ABSTRACT OF THE DISCLOSURE         A rescue breathing device or insufflator is shown for providing mouth-to-mouth artificial resuscitation to a victim of suffocation or asphyxiation.  The device has a tubular body comprising an input portion and an output portion.  The tubular body has a central axial air passageway converging in cross-sectional area in the input portion to a central venturi region.  At least one fresh air port communicates with the venturi region.  The air passageway in the output portion diverges or is of constant cross-sectional area, so that a venturi effect is produced when the device is used, resulting in the venturi mixing fresh ambient air with the respirated air provided to an asphyxiation victim by a rescuer, thereby increasing the oxygen content of the air delivered to the victim by the resuscitation process.  A shield is removably mounted of the tubular body to provide a good seal and prevent lip contact between the rescuer and the victim.

Abstract: ABSTRACT       The catalyst and process for simultaneously hydrotreating and hydrodewaxing of hydrocarbons of this invention relates to the catalytic treatment of hydrocarbons in the presence of hydrogen and under conditions of elevated temperature and pressure.  A method of treating raw shale oil by first contacting the oil with a hydrotreating catalyst to reduce organosuifur and organonitrogen content, and then contacting the shale oil with a hydrodewaxing catalyst, is known. However, this method also results in undesirable proportions of organosuifur and organonitrogon components, and results in an excessive degree of indiscriminate hydro-cracking of hydrocarbons other than waxy paraffins and an Inefficient use of hydrogen in lowering the pour point of the hydrocarbons treated The present invention overcomes these problems by providing catalyst compositions and process conditions for selectively hydrocracking the waxy paraffins and substantially reducing organosuifur and organonitrogc-compounds in hydrocarbon feedstocks.

Abstract: ABSTRACT         Resin coated sand for foundry shell molding operations is provided which eliminates the cracking of the molds at the time of pouring.  In conventional phenolic bonded sand molds, the abrupt thermal expansion caused by the pouring of the molten metal into the mold causes the mold to crack.  The resin coated sand, in this invention, is composed of foundry sand or aggregates coated with a phenolic resin which has incorporated therein, a polyethylene glycol of high molecular weight.  This improved coated sand eliminates cracking at pouring and does not impair the shake-out property of the molds.
